Synopsis

Two vulnerabilities have been found in GNU cpio, the worst of which
could result in execution of arbitrary code.
Background
==========
GNU cpio copies files into or out of a cpio or tar archive.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 app-arch/cpio < 2.11-r3 >= 2.11-r3
Description
===========
Two vulnerabilities have been discovered in GNU cpio:
* The list_file function in GNU cpio contains a heap-based buffer
overflow vulnerability (CVE-2014-9112)
* A directory traversal vulnerability has been found in GNU cpio
(CVE-2015-1197)
Impact
======
A remote attacker may be able to entice a user to open a specially
crafted archive using GNU cpio, possibly resulting in execution of
arbitrary code, a Denial of Service condition, or overwriting arbitrary
files.
Workaround
==========
There is no known workaround at this time.
